An Investigation Of The Effects Of Solid Solution Temperature On The Wear Performance Of Aged AA7075 Alloy
Journal Title: Gazi Üniversitesi Fen Bilimleri Dergisi Part C: Tasarım ve Teknoloji - Year 2018, Vol 6, Issue 1
Abstract
In this study, the effects of different solid solution temperatures (465 °C, 470 °C, 475 °C, 480 °C and 485 °C) before aging heat treatment on the microstructure and wear behaviors of AA7075 were investigated. Scanning electron microscope was used for microstructure examining of aged samples. Wear tests were performed on pin-on disc type wear device at 1.5 ms-1 sliding speed with four different sliding distance (500 m, 1000 m, 1500 m and 2000 m) under 30 N loads at room temperature. As a result of the study, the hardness values were increased with increasing solution temperature. In the wear tests, the lowest weight losses were determined in the solution treated at 485 °C and aged at 120 °C for 24 hours in AA7075 alloy. Generally, it was observed from worn SEM images that both abrasive and adhesive wear mechanisms were active.
